To all whom it concern;

Be it known that I FRED W. LEUTHESSER, a citizen of. the United States, residing at useful ImprovementinValves for Radiators,

This invention pertains to that class of air valves rfor radiators in which the heating medium employed is steam and WVhlOh is generallyterme'd or known'as the radiator will settle onremain in-t e valve and will interfere with the'correct operation of the air, unless dischargedor drawn. oil in order Theobject of the present invention isto construct and apply to an air valve a drainage spout which will-be effective and reliable chamber of the valve any water of condensaleadingfromf the radiator to the valve from beconilngclo ged or stoppedby sediment or other materizfi. a The invention consists in the features of construction and combinations of parts here inafter described and pointed out. in the In the drawings Figure- 1 is. an elevation partlyinsectio'n of an air valve forradiators, showingthe drainage spout inserted in position in theattachingnlpple for the. valve to the radiator; Fig.2; a cross section-throughthe attaching nipple and the drainage spout; Fig.- -'3 a erspective view of'the drainage spout; an Fig. 411. plan view'of the drainage p The air valve, in the construction shown, has a base or cup 1 inclo'sing a"chamber 2, and having a nipple 3.011 one side with apassage 4, by means of which nipple the air valve is attached to or connected wlth the radiator, so thatthe passage 4 furnishes communication between the-chamber ;of the valve and air and steam between the radiator; andvalve, as usual in; the type of air valves for radiatorsishown.

The drainage spout Sloan be made of sheet ,the drainage spent to which this invention metal or other .suitable material bent into a horizontalmemb'er'l, with thefhori- 'pro'ection' 18 to in position, locatedwithin the passage-.4 of

I the nipple, as shown in Fig. 1. The form of the drainage spout as shown, is of a t l-shape m cross section, The passage 8 of the spout as a w ole constitutes a conductor and drainer orfremoving the water of condensa tionfornied in; the chamber of-the valve. The valve shown has on the up er side of the base or'cupl an annular Wal or flange 10, with an'interiorscrew thread,.into which 1 is threaded the lowerend of the'outer shell 'or casing .11 of. the valve; and the-valve has an expansible member or stem 12 socketed onto a pin orstu-d 13 upwardly projectingfrom the bottom-of the base or cup 1 of the" valve. I, The valve shown is of that type .of

air valves employing a float 14 operating within the chamber of the shell or casing. The upper end of the outer shell creasing 11 has a neck 15 with a, closing cap 16, in which neck is'located -a;valve'seat to ciact with a pin valve carried'by the float 14, the seat and valve being of theusual construction, and,

- therefore, not shown.

The drainage spout is held in position, by

. having the side walls of the horizontal member 7' of the spout extended to form side forks 17, each forkterminating' in a projecs 'tion 18 having a s uare shoulder, as -shown in Fig. 6. -Said for or arms 17 are. elastic,

so'that they will spring toward each other;

and allow the horizontal member of the spent to beinserted in the passage 4, and, when-fully inserted, the side arms or forks will spring outward for-the shoulders of the age the face of the inner W of the base adjacent to the nipple and retain the spout in its inserted position. i

It-Will be understood that the valve with the drainage spent in modified forms, has,

in the construction shown, the base or cup 1 with'chamber 2 and the outer shell or casing 1'1, expansible member or stem 12, and float 14, as described-for the construction of valve shown in 1-.- These parts are of the usual andiwell known form of construction for: an valves for radiators, having an expansible member or stem and a float and operating in the usual manner of such valves, so that itg'i's not deemed necessary to speciftion ofthe parts of the .airvalve outside of specifically pertains. The nipple, instead of icallydescribe the' construction'and opera-- project out from one side of the outer shell or wi flow through the channel or passageway formed by the side walls of the spout, by which any accumulation of water in the chamber of the valve will be drawn off'therefrom and will flow downward on the vertically depending member of the spout and enter the radiator, leaving the chamber of the valve free of water to an extent by which a free passage for air and steam is provided, without any liability of a seal being formed by the water of condensation in the chamber of the cup or the casing of the valve that would interferewith the venting of the air and the admission of steam from the radiator.

The formation of the sprin fork is one which permits the valves to e completed and assembled prior to the insertion of the drainagespout which can be permanently fixed in place merely by pushing it into the nipple until the shoulders on the forks of the spring engage the inner wall of the base or cup. This obviates the necessity for upset- I ting the edges of the inner end of the spout,

which hasfrequently been the practice in the prior constructions and permits the parts to I from the cham spout bent to furnish a horizontal member,

be much more readily and satisfactorily as sembled, and permits the valves to be packed and shipped in compact form and the drainage spouts to be thereafter inserted, which is .a more satisfactory method of packing an shipping than would be the case if it were necessary to insert the drainage spouts prior 'to the final assembling of the parts composing the valve.

What I claim'as new and desire to secure by LettersPatent is:

1. In anair valve for radiators, the combination with a laterally extending nipple,

for attachment of the valve to the radiator, having a passage leading through the nipple from the chamber of the valve of a drainage spout provided at its inner end with a spring fork having shoulders adapted to engage the adjacent portions of the interior of the valve to prevent the withdrawal of the drainage spout, substantially as described.

2. In an air valve for radiators, the combinationwith a laterally extending nipple for attachment of the valve to the radiator, having a'passage leading through the nipple er of the valve of a drainage and a downhanging member, the horizontal member being entered into the passage of the nipple and having at its inner'end a spring fork provided with shoulders adapted to engage the adjacent portions of the valve structure to prevent the removal of the draw-oil spout, substantiallyas described.
